Abstract

L’invention concerne un procédé de fabrication d’un élément à pôles magnétiques (1) comprenant les étapes suivantes : - la fourniture d’un bloc d’aimantation comprenant une première face principale (11) et une seconde face principale (12) délimitant entre elles une épaisseur du bloc d’aimantation ; - l’usinage, sur une partie seulement de l’épaisseur du bloc d’aimantation, d’un premier ensemble (21) de rainures initiales (20) à partir de la première face principale, de telle sorte que le bloc d’aimantation reste d’un seul tenant ; - le coulage d’un premier matériau de liaison (30) dans les rainures initiales ; - l’usinage d’un ensemble de rainures complémentaires (40) formant des prolongements des rainures initiales du premier ensemble sur toute l’épaisseur du bloc d’aimantation, de manière à former une pluralité d’aimants unitaires (2) séparés les uns des autres, les aimants unitaires étant maintenus solidaires par le premier matériau de liaison. Figure pour l’abrégé : Fig. 4
